Starting Saturday, we will no longer be updating the map regularly, unless there is a major flare-up. But our reporters and photographers will continue to be at the scene and will be posting regularly to L.A. Now.

Firefighters now have 42% of the fire's perimeter surrounded, mostly on the northern and northwestern flank near Acton and Agua Dulce, and the southwestern flank above the foothill communities of Altadena, La Cañada Flintridge, La Crescenta, Glendale and Sunland-Tujunga.

The fire continues burning to the west, where fewer than a dozen homes remained threatened in a remote area in Pacoima Canyon. Officials said battling the flames was difficult in an area with tall, heavy brush and steep slopes. To the east, the fire was moving slowly through the San Gabriel wilderness, and remained more than five miles from the suburban communities of Sierra Madre and Monrovia, which are not threatened at this time.

Farther east, at the edge of the San Bernardino National Forest, firefighters reported good progress battling the two fires east of Yucaipa, the Oak Glen and the Pendleton fires. The Pendleton fire was declared 100% contained at 7:15 this morning, burning 860 acres and destroying one home and one outbuilding. To its east was the 1,159-acre Oak Glen fire, which has destroyed one home and one outbuilding, and damaged another home. It was 95% contained. Officials expect that fire to be contained by Monday.
